Chia is an edible seed that comes from a member of the mint family that grows abundantly in southern Mexico. In pre-Columbian times it was a main component of the Aztec and Mayan diets. Aztec warriors carried it as a survival food. It has been written one tablespoon could sustain a warrior for a whole day. Omega-3 fatty acids are abundant in Chia seeds, even more so than flax seeds. And it has another advantage over flax: chia is so rich in antioxidants that the seeds don’t deteriorate and can be stored for long periods without becoming rancid. And, unlike flax, they do not have to be ground to make their nutrients available to the body. Chia seeds are high in fiber as well as calcium, phosphorus, magnesium, manganese, copper, iron, molybdenum, niacin, and zinc.
